Why quickly discharges battery, how to find and eliminate the cause

The removal of technical malfunctions of the car should not postpone "for later", because to lose a favorite means of movement for a long time - the test that the truly motorist is quite difficult to withstand. Moreover, in our time, find a fault and try to eliminate it with your own hands quite possibly, numerous sites for motorists give detailed information on the principles of operation of each vendor of the car, possible damage and repair. Let's figure out today with the principle of the battery and the main problems, with it connected, which often occur during the operation of the car.

The automotive battery design is quite simple: in the device body having a rated voltage of 12 volts concluded 6 consequely interconnected independent batteries with voltage in 2 volts. As a material for the manufacture of housing and separators, distinguishing banks with a set of separated plates, acid-resistant plastics or ebony are used. The case has compartments, battery cans are installed in them.

The pole plate is a lead grid with a porous structure pored cells, which makes it possible to increase the contact area with electrolyte. For the manufacture of an active porous substance, lead powder and sulfuric acid are used. The material used for the manufacture of negative plates further comprises a sulfate barium.

In the process of the formation of the battery, the plates are charging, the active ingredient in the plus plates is converted to lead dioxide, in negative - acquires the spongy structure.

Prepared battery banks are filled with an electrolyte, which is a mixture of distilled water and sulfuric acid. The battery operation begins at the time of the load connection - this action leads to the movement of charged particles, as a result, the current is produced.

As a rule, car batteries are acid-leading devices with a voltage of 12 volts, a charge capacity model is distinguished.

Among the basic requirements for modern batteries:

• compactity
• ability to produce big currents
• easy service
• minimum internal voltage drop
• low self-discharge during operation

All these requirements sufficiently correspond to acid-lead batteries.

In modern automotive industry, we found the use of three types of electroactors:

• lead acid, most common thanks to the available cost,
• most recently appeared lithium-ion, which is truly a revolutionary invention, which is surprisingly quickly conquering the market, the product is very promising, as it is ideal for installation on electric vehicles
• it is ironic skinless, distinguished by high technical qualities, but due to its high cost has been manufactured by limited parties and used to a greater extent in military engineering.

Considering the demand for battery devices in the automotive industry, active work is carried out by their improvement, for example:

• the use of gel-shaped electrolyte on a silicon basis - in order to eliminate water loss and improving operational qualities
• electronic diagnostic chips - allowed to perform a subtle adjustment of each of the cans
• the use of a graphite and carbon framework is to substantially facilitate the battery and reduce its dimensions.

Why car battery

Modern car imagine without a battery is very difficult - thanks to it, it is powered by the controls of control and onboard circuit services when the engine is turned off.

In the process of operation of the engine, the battery connected to the generator is a load, but at the moment when the total load created in the electrocups begins to exceed the power output by the generator, the battery turns into an electricity source that helps maintain 12 volt voltage in the onboard network.

But the main task of the battery is to act as a starter at the time of the car factory.

Attempts to replace the automotive battery to pneumatic motor startup devices and condenser storage facilities failed.

But with the apparent well-being, modern accumulating devices are still not devastable, including:

• the number of cycles of their discharge - charging has limitations.
• plates are subjected to irreversible sulfate processes, which leads to a significant reduction in the capacity of the device and a decrease in its service life
• low mechanical strength of electrodes,
• the possibility of sinking the electrode mass and the destruction of the separator, as a result - the threat of closures of the anode and the cathode
• ability to loss of performance due to long-term storage in the discharged state

Given all the above factors, it can be assumed that the problems with car batteries during operation is not rare. Therefore, it makes sense to consider Read more.

Causes of rapid discharge of the battery operated

Often there are problems with too fast battery discharge. You can monitor the operation of the battery in a modern car that can watch the indicators that show the electrolyte density and the charge level.

But you can only navigate about these devices. A more informative can be a battery charging light on the instrument panel. When the ignition is turned on, the bulb has a battery type, and immediately go out.

An alarm signal will be a glow of this light bulb when the engine is on - experts recommend checking the operation of the indicator, the operation of the car is recommended to be refused to determine the exact cause of the breakage.

Depending on your own knowledge in the field of repair and desire, you can deal with the situation or refer to the specialists of the service center.

Approximate lines of the automotive battery service - 3-5 years, its duration is caused by the quality of the instrument and operating conditions.

The situation when problems begins with the battery creates a lot of inconvenience to the car owner, i.e. Development will need to be repaired immediately. Why should I start searching?

wired electrical wiring, how to find and eliminate

• make sure there are no oxidized sections of wiring, broken or paperless wires
• explore the integrity of the connecting terminals.

Next, check the battery power - in some cases, the dilapidated device with increasing power cannot fully discharge, powerful - can recharge with excess energy, which negatively affects the functionality.

the electrolyte of the battery does not meet the requirements of how to find and eliminate

After examining the battery, make sure that the electrolyte has not changed the color. The darkened liquid is a clear symptom of discontinuing the plates, the replacement of the battery in this case is required.

The cause of such a phenomenon can be the operation of batteries charged by 50-60% for a long time.

The destruction of the battery case may occur due to the effects of too low temperatures (freezing) on \u200b\u200bthe discharged battery.

When checking the generator, it may turn out that it is poorly charged. The usual cause of a reduction in the charging voltage lies in a weakened tension of the generator drive belt.

It should be noted that the acceleration of wear in violation of the rules of operation can be so strong that the battery failure can occur during the warranty period.

the battery model does not fit the car, how to determine and eliminate

The cause of the car malfunction can also be the inconsistency of the battery model of the vehicle characteristics to which it is installed, the capacity generated may not be enough to perform the entire amount of work.

It should be borne in mind that when operating at the same conditions, a battery with a large container will last longer. Very important for automotive batteries is the starting current indicator, i.e. What strength can be given the battery at low temperatures in 30 seconds. It is required for starter at the time of launch. The main difference of autoaccumulators is the ability to produce large currents, traction batteries, even at high tanks, cannot be issued such a current.

does not correspond to the battery power, how to determine and eliminate

Choosing AKB must take into account the recommended manufacturers with a container, set the aggregates with a higher or low capacity is not recommended. In the extreme case, you can resort to the installation of the battery with a capacity exceeded by the recommended no more than 15%, otherwise the charging will not occur in normal mode, as a result - reduction of service life and problems with the start of the motor.

Using ACB of lack of capacity can cause problems with the launch of the motor, work on the verge of possibilities will significantly reduce the service life of the device.

the battery is recharged, how to determine and eliminate

With the problem of recharging, motorists are quite common. The problem is that the battery charged to sufficiently does not cease to be charged even when the electrolyte is gaining the necessary density. The continuation of the charging process leads to the fact that the aqueous part of the electrolyte disintegrates into the components: oxygen and hydrogen, the process of "boiling" begins, the amount of water included in the electrolyte will decrease. It looks like this is the classic recharge of the accumulating device.

Boiling with evaporation will inevitably lead with a decrease in the electrolyte level, which is quite dangerous for the battery: if the incomplete charge simply does not allow you to start the car, then the reload can cause an explosion of the battery.

The relear may occur if the operation of the controlling the controlling of the generator is broken, i.e. When it reaches 12.7 volts, it will not turn off the power supply from the generator. When the relay breaks, the charging process will continue constantly, given what currents will go from the generator does not have to doubt that the battery will boil fast enough. Elimination of the breakage is carried out by replacing the relay, it has a small cost.

If there should be no doubt about the normal operation of the generator and the relay, it should be verified in the normal functioning of the sensor, it, like any other mechanism, may fail and give distortion.

To seek the cause of recharging and to eliminate it in a timely manner - necessarily, the negligent attitude to the problem can cause:

• boiling and splashing electrolyte, as a result - the oxidation of the terminals, damage the metal of the body, wires,
• gentlement, and then squeezing lead plates, which can lead to the final death of the battery,
• the explosion, as a result of which the acid will fall on the entire part of the car.
• fuses failure, because They are 17 volts are not calculated,
• heating relay, up to refueling, in some cases such a phenomenon may cause a fire or wiring.

It should be noted that the controlled recharge process is sometimes resorted to intentionally, in order to increase the electrolyte density to the optimum level, the indicator 1, 27 g per cubic cm will excel the possibility of its freezing when the temperature decreases to minus values.

faulty generator, how to find and eliminate

The generator may also be out of order, it is possible to assume such a breakdown in case the relay was replaced with a new one, but the problem was not eliminated. Repair or replacement of the generator - the procedure is more complex and will require the cost of time and means.

In the absence of skills and deep knowledge on the topic, it will be easier to refer to the experienced master from the service center.

We watch the video on how to check the generator:

Causes of the rapid discharge of a new battery, reasons, how to find and eliminate

Over time, the quality of the battery may decline, this is a natural process, but a new battery can also be discharged.

The search for reasons should be started with checking the electrical wiring, for this you can use a regular voltmeter. It will be necessary to compare the voltage indicators on the generator and the battery when the engine is running.

There will be different voltage to indicate a different voltage, for example: on the 14 V generator, on the battery - 13.5.

Correct the situation by checking the contacts.

If, when changing the voltage on the contacts of the generator, the testimony will be less than 14 V, then this will indicate the generator failure. In this case, it can be done on your own - so it is to determine the length of the brushes, it should be at least 8 mm.

If there are no deep knowledge in the field of automotive electrician, then for further diagnostics, breakdowns and eliminate it is better to contact the specialists in the service center.

If the voltage is higher than 14 V, then the battery is recharged.

If the battery is discharged, what to do to the driver

When you try to start the car, it was found that I got a battery, as the driver should act in such cases?

The most reliable option is to stop passing past the car and ask to help, namely, connect your car to his battery.

But not all modern vehicles are adapted to perform such a procedure - access to the battery may be limited.

The second option is to purchase a special battery charger, you will need:

• unscrew the plugs
• connect the instrument to the battery and set the current consignment of 10% of the battery volume
• track the readings of the charge volume sensor.

The third option is to ask for someone on a tug or try to start a motor with a push.
